Hand/Arm Update:
- juerg replied 10 years, 2 months ago
  
  So you impress us with a shiny underarm part! I assume this is the result from some additional treatment and not the output of your ultimaker?
- RentaPrinta replied 10 years, 2 months ago
  
  Hello Jörg,
  
  its a product of the ultimaker, but after printing i do a lot of polish and varnish:
  
  Here is a manual how i do this:

Maker-Faire 2104 Update:
Marten de Groot posted an update 10 years, 2 months ago

Here some pictures from the new ServoBed:
I’ve replaced two servo’s more to centre, to get some more hight.
I’m almost finished with the last RotaWrist parts.
When these are ready, I need to check the RobCableFront part.
I need to (re)move some holes in this part.
Marten de Groot posted an update 10 years, 2 months ago

Last night and today I’ve printed all the RobParts.
Now I’m printing a new ServoBed and tomorrow I will start with all RotaWrist parts.
When that’s ready, the complete ForArm and Hand are ready for use 🙂

Marten de Groot posted an update 10 years, 2 months ago

So, during some spare time this day’s, I’ve printed a complete Right hand.
All in PLA and everything fits well 🙂
My next step is to start with the Right underarm parts, so I can install all servo’s and connect these to all the Fingers.

Here some pictures from the complete Right hand:
- Gael Langevin replied 10 years, 2 months ago
  
  Woouuiii !
  Nice prints! Well now the forarm and you just about ready to have a Right hand!
  - Marten de Groot replied 10 years, 2 months ago
    
    Haha, I can’t wait…
    I’m printing the last day’s at Day and Night… 🙂
    I hope the forearm is ready in about two day’s.
    
    Next day’s I will check all the lengths which each finger needs to lift them completely with the new servo pulley.
    So I can start re-designing the pulley for each finger.

Here a video again, with the new servo pulley which is specially designed for a Finger movement.
It’s designed for servo’s which can turn a full 180 degrees.
This Pulley gives a better torque and there’s less change to move to much to destroy the servo or finger.
There are two option about the spring (in this video I’m using a elastic cord…[Read more]
- Gael Langevin replied 10 years, 2 months ago
  
  Nice!
  So the white is the elastic cord and it runs all the way to the end of the finger, if I juge the white spot at finger tip.
  What kind of elastic cord? Don’t you think it will stretch more and more over time?
  I also can see the asymetric effect on the black braided line.
  - Marten de Groot replied 10 years, 2 months ago
    
    Hi Gael and thanks for your comment and time 🙂
    
    The elastic cord is a basic peace which you normally will use for clothes.
    It’s now just to do the job of the spring.
    I’ve ordered some springs and have to wait they will be here.
    
    I hope the asymmetric effect is in a positive way 🙂

Here some better pictures the new servo Finger pully together:
- Gael Langevin replied 10 years, 2 months ago
  
  Interesting design! I like the idea to set the servo horn within the pulley. They might be a bit too thick to fit under arm covers though… Let us know.
  - Marten de Groot replied 10 years, 2 months ago
    
    Thanks Gael,
    
    And good to now about the limited thickness.
    I will check this when all underarm parts are done.
    There is a easy way to save some hight if needed, I can include some holes for the two screws.
  - Marten de Groot replied 10 years, 2 months ago
    
    Hi Gael,
    
    Just checked the hight and it fits fine.
Marten de Groot posted an update 10 years, 2 months ago

I’ve made a other servo pully.
I hope to get soon the springs because they are needed in this design.

- juerg replied 10 years, 2 months ago
  
  Hi Marten
  I think before changing the pullies we should agree what the mechanical requirements are for the fingers.
  In my arms I use mg996R and they can turn about 110 deg to the left and to the right (total 220). So when Gael says he can move all fingers with the exception of the middle one with an unmodified HK15298 servo which allows only 45…[Read more]
  - Marten de Groot replied 10 years, 2 months ago
    
    Hi Juerg,
    
    Thanks for your input about this.
    
    The good thing to use a 180 degrees pully, is that there is less change to break any mechanical parts.
    A other good thing is, there is a higher resolution to place/hold the finger at his position.
    Have you seen my Finger Starter video ?
    Here I’m using a MG996R servo and it turns a full 180 degrees…[Read more]
    - juerg replied 10 years, 2 months ago
      
      Agree that individual pulley’s for your combination of servo and finger would be safest for builders. Just go 0 to 180 without having to worry about limits.
      I am rather the software guy and think – once the mechanical part looks good – I can control movements with the mapping function of MRL.
      For me the springs are rather an option to add a bit…[Read more]

First test of the servos. The neck works fine. Jaws needs to be changed to increase the speed of movement. Eye servos tested but not connected to the eyes.
- oldfarmhand replied 10 years, 2 months ago
  
  That looks like a very good design I really like the eye movement
- Gael Langevin replied 10 years, 2 months ago
  
  Hey cool ! Thanks for posting the video!! I love to see stuff like that. Yes the speed of the jaw needs to be increased. Bob Houston has made a remix for the eyes, I wonder if it fits in one normal InMoov head.
Marten de Groot posted an update 10 years, 2 months ago

I would like to add a bit more control of the hand to keep it more horizontally (things tend to fall off Marvin\’s hands). Any success stories or frustration reports about that?

  Hello,
  I have found a pretty good solution last year. I didn’t post about it because I wanted to test it before. The hand was set up at an exhibit running the whole day for nearly two months, and the result was concluant.

    It’s good to have control of the string length at the pulley, maybe your tutorials should include this update?
    For the springs – I think it’s good to keep the strings under tension – great pictures and nice cabeling! But e.g. a bit of a fragile object might still be broken because the servo won’t stop?

    - Mats Önnerby replied 10 years, 2 months ago
      
      The basic problem is that the you need to pull a longer distance in one direction that the other. For example the major finger needs to be pulled 27mm to close but only 17mm to open. So the servo pulleys needs to be redesigned to have two different lanes, with different diameters. I have started to experiment, but the pulleys I try now are to…[Read more]
      
      Gael Langevin replied 10 years, 2 months ago
      
      @juerg, the servos won’t break parts, at least it never did on any of the hands I have assembled. In MyRobotLab you set the Min and Max for each servo, this avoids the servos to force further than necessary.
      The pulleys mounted on the HK15298, even though it rotates only 90 degrees, can actuate fully all fingers, only the Majeure finger is…[Read more]
      
      Mats Önnerby replied 10 years, 2 months ago
      
      Thanks for posting the spring design. I think springs has to be part of the solution, since turning the wrist will pull on both sides of the servos. A different design of the pulleys may decrease the length that the springs need to flex.
      
      Marten de Groot replied 10 years, 2 months ago
      
      Springs will the best/easiest way to solve the problem.

      0.4mm will do the job, but might carve in the plastic after a lot of usage.
      One of the InMoov hand I made was exposed in Paris Tokyo exhibit for nearly two months working everyday from 10 AM to 12PM, the 0,8mm braided line didn’t carve in the plastic, I was pretty surprised about that.
      
      Stefan Ekstam replied 10 years, 2 months ago
      
      Ah yes, I was afraid that carving of the plastic would be a problem. I’ll use my 0.4mm for the simpler finger tester then, just to be able to test something. 🙂
      Quite impressive that the hand could do that much work without breaking. You’re clearly in the industrial quality segment here. 🙂

  Hey nice Marten!!
  I like that Carbon PLA. I remember the parts you showed me in Eindhoven, the quality was very good!

Just finished the last finger pieces for the Finger Starter Kit.
All are printed with CarbonFil with a 0.2mm layer hight.
(I now, it’s better to use 0.1mm 🙂 )
- juerg replied 10 years, 2 months ago
  
  Hey looks great. Many, many more parts to print however …
  I give a filing to the finger parts where they move against each other because the printing in layers creates imperfect vertical surfaces.

    I don’t now yet with the fingers.
    The CarbonFil is great stuff and feels strong.

    And it didn’t break 🙂
    For now I’m still waiting for advice about which glue I can use for this CarbonFil.
    
    I will come back to this question if I now more 😉

      Hi
      thanks for your comment. What is your print bed made of and what temp / preparations do you need to make the pieces stick to it?
  - Sebastien replied 10 years, 2 months ago
    
    I got the same trouble. Happily with abs it can be repaired quickly with acetone.
    Some times after I found this tip, just heat to smooth the holes. It looks like Mats Önnerby tips with airgun to mount pla parts but with a solder iron.

      Hi Juerg and Sebastien,
      
      I’m still using the standard clean glass plate from the UM2.
      After each print, I’m cleaning the plate directly when it’s still hot.
      
      For CarbonFil I’m using a temp from 255 C and the heated bed is set to 60 C.
      I’m still playing with some settings.
      Most important thing is that the plate needs to be levelled well and very…[Read more]

      I think I will sit down and create a video about my finger assembling techniques including the strings. Watch out for it.
- Gael Langevin replied 10 years, 2 months ago
  
  Great prints Marten!
  In the video posted by Sebastien, the idea is great! Specially if you drilled the holes a bit too wide.
  But be sure that finger stays loose, in the video they are stiff, rigid, and that is not okay for the movement. The finger should move freely at each joint.
  - Marten de Groot replied 10 years, 2 months ago
    
    Haha, yes the video is good for all the joint parts.
    
    I was more focused how to glue all fingerparts together like part-1 with part-2 etc….
    CarbonFil is PET based and PET is difficult to glue normally.
    I hope the 30% of carbon-mix will make it easier to glue this together.

    It looks to be kept secret what material it is. It is also rather expensive but after having encountered so many problems I gave it a try (beside other materials) – and at least for me and my PLA-HT it works like a charm.

- Gael Langevin replied 10 years, 2 months ago
  
  Buildtak didn’t work with ABS for me, I managed to nearly destroy the surface after the third print. ABS temperature is too high for the Buildtak and causes to scare the surface rapidly. I didn’t try with PLA. But I have seen very good results at various 3D print shows.

    I use a Raspberry PI Camera module connected directly to the Raspberry CSI port. I has really good quality for still pictures and video stream is OK.

      Others have tested the Raspi Camera module into MRL with success. Your errors might be related to which version of MRL you are using.

This is a part of the Bicep. I use PLA, and it's not as soft as ABS. So when I tried to mount them together, it was impossible, because it wouldn't flex.

  Very nice Markus! Using a wide screen is good, I have chosen a much smaller screen to be mounted on the Odroid U3 and it is a bit hard to read on it.

  Super! are you using the Neo Pixel Ring I use or is it done with color leds? If you use the Neo Pixel Ring, is it hooked to an extra Arduino or is it implemented within the two InMoov Arduinos?
